WebThe net rate of discharge from the extruder is equal to the alge-braic sum of the drag flow, the pressure flow, and the leakage flow. Equation 1 is the flow equation for the extruder, which is really a material balance made under the assumption that the liquid is incompressible. Q = Qd — Qp — Ql (1) Neglecting the leakage flow, which is ...

Simplified Flow Theory for Screw Extruders - EDGE

WebJan 10, 2024 · The flow of polymer in co-rotating machines is the result of the movement of the screws relative to the barrel, as well as the pressure gradient in the machine. It is the pressure-drag flow which takes place in open channels between screws (alternately one and the other) and the barrel. 2.2.
